Well, I wasn't ever in favour of using fourcc codes since they're just not standardized at all, highly redundant in some cases and also miss lots of stuff we actually need (like all the rgb formats). Cc'ing the heck out of this to get kernel people to hopefully notice. Maybe someone takes charge of this ...

But given how fourcc works we probably have that already, just haven't noticed yet :( -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
